- Vegetarian and vegan diets are associated with lower overall cancer risk compared to non-vegetarian diets.
- Specific cancers with reduced risk include stomach, colorectal, colon, pancreatic, melanoma, breast (especially postmenopausal), bladder, and non-Hodgkin's lymphoma.
- Vegan diets show reduced risk for total cancer and breast cancer, but results for other cancers are less consistent.
- BMI partially explains the associations between diet and cancer risk.
- Evidence strength varies, with probable causality for vegetarian diets and total, colorectal, colon, and breast cancers, and limited-suggestive for others.
- The study supports adopting plant-based diets for cancer prevention but calls for more research on long-term adherence and less studied cancers.
